' It? is one object of the present invention to pro-vide adevice .which permits application, tightening and removal of anti-skid chains without the necessity of reaching behind the tire duringthe entireoperation,

Referring now to the drawings in detail, one set of ends i and 2 of the .main long chains C are secured to a channel shaped metal bar H], said bar ill-being shaped to fit the contour of a standard tire. Chain end I is attached to hole 3 provided in upper end I! of member ID, while chain end 2 is attached to hole 4 in the projecting tongue 23. The opposite set of ends 5 and 6 of the chains C are secured to a pair of cables l2 and 18. As shown in Figures 3 and 6, cable l2 enters a tubular section l9, which is integral with bar Ill and extends through the entire length of said bar l0. Cable l2 passes through this tubular section, then passes through the retaining ring l3, and is wound up on one side of a drum IS. The other cable is passes directly through the ring 13 and is wound up on the other side M of drum l6. s

As shown in the drawings, the drum I5 is pivotally connected by bolt 2| at 22 to one end of the bar Ill. This end of the bar is provided with a right angle flange which is secured to ring l3 by fastening means 20, as shown in Fig- 8 Claims. (01. 15292155] .1 2 are 61. As best shown .in is x-dixrided;v into. a compartment I l, which re.- ceives cable l8, andrcompartment l5,.which:receiveszcable, l2.'.2 .'Ihe outer. wall. i'l of drum. l6 isprovidemwitha nut; i'l', and the cablesmay be.;.wound up by means. 1011a. crank; (notv shown)=, which isuslipped over nut H'. The back Zl-of thedrum.has teethcut into its periphery and these teeth are adapted-to beengaged by pawl,

In operation: the. bar lUi is placed on; the giioundslightly in front of 513118 left rear tire-the unit. being made: reversed for. the right. side-- andathe loose cable i2 is laid. close to the tire; The-same is done-on the .rightside. The car is:

then driven forward until'the tire rests on bar iii-9 The chainsare then slipped over the tire and spaced evenly. Thenthenut I is engaged witlr-acrank and rotated, thereby making thechains-l-and fi "taut; Thechai-ns are held-in this condition byJth-e action of pawl 2%.

- When it'--is-desired*to remove the chains, the car is brought to rest with bar E0 in contact with the ground. The pawl 23 is released and the cross link of chains between chains l and 2 is grabbed and pulled toward the rear of the car, thus extending the cables to their full length. The chains can then be slipped over the tires and the car driven back over the cables.

As shown by the above description, it is not necessary to reach behind the tire during the whole operation, as all work is performed in front. Furthermore, it is easy to make and keep the chains taut in the above described manner by means of the device embodying my invention.

It will be apparent from the above description and drawings that the present invention is not limited to the details described above and illustrated in the drawings, and may be carried out with various modifications Without departing from the spirit and scope of the invention as defined in the appended claims.

What is claimed is:

1. An anti-skid device for tires, comprising, in combination with anti-skid chains, a channelshaped member fitting the contour of the tire, said member being securablyat-ta-ched at one end thereof to tensioning means, said tensioning means being provided with two cables, one end of this. figure, the. drum each said cables being attached to a free end of said anti-skid chains.

2. An anti-skid device for tires comprising, in combination with anti-skid chains, .a channelshaped bar fitting the contour of the tire, a drum having a rear supporting member securably attached to one end of said bar, said drum being adapted to receive and wind up two cables, said cables being attached at one end to said anti-skid chains, the other ends of said chains being fastened to the channel-shaped bar and the rear supporting member of said drum respectively.

3. An anti-skid device for tires, comprising, in combination with anti-skid chains, a channelshaped bar fitting the contour of the tire, a drum having a rear supporting member securably attached to one end of said bar, said drum being adapted to receive and wind up two cables in separate compartments thereof, said cables being attached at one end to said anti-skid chains, the

other ends of said chains being fastened to the.

channel-shaped bar and the rear supporting member of said drum respectively.

4. An anti-skid device for tires comprising in combination with anti-skid chains, 9. channelshaped bar fitting the contour of the tire, a drum having a rear supporting member securably attached to one end of said bar, said drum being provided with a, ratchet mechanism and being adapted to receive and wind up two cables in separate compartments thereof, said cables being attached at one end to said anti-skid chains, the other ends of said chains being fastened to the channel-shaped bar and the rear supporting member of said drum respectively.

5. An anti-skid device for tires as described in claim 4, said channel-shaped bar being provided with an integral tubular section which extends through the entire length of the bar and through Which one of the cables is passed.

6.
